Android back problem

I have three activities, from A it is going to B, from B it is going to C. I am using following code to transfer from one activity to another.

Intent intent = new Intent().setClass(this, B.class);
startActivity(intent);

I want that when I use the back button, it should come to B if it is at C(which is ok for me), but if I use back button at B activity, it should not go to A, it should directly go out the application. How it can be arranged?

In class A you would put:

Intent intent = new Intent(this, B.class);
startActivity(intent);
finish();

This will remove class A from the Activity stack.

There you go

 @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK)) {
            this.finish();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }

Override the member function onBackPressed() inside your Activity class.

Example:

public void onBackPressed() {
    Intent intent = new Intent().setClass(this, B.class);
    startActivity(intent);
}
